Everytime my car is in park and I put it in reverse and then drive forward, there always seems to be a buzzing noise when I turn the wheel or even if I don't turn the wheel. Or when I turn sometimes and straighten out my wheels out of the turn I hear the buzzing noise again. I don't think its tire rubbing because my car isn't even lowered. I think it has something to do with the suspension or my wheels/brakes/rotors or something.

Someone give me some opinions or infos
Thanks

 

My guess is that it's:

A search for 4mph will turn up this disscussion thread:

abs / traction control self test you get it 2 times once below 5mph and once between 7 and 12mph

 

 

Gotta be, I have the same noise. Always wondered what it was, makes sense now.
